Here is some weird shit.

New install of ZT on machine off campus. No static IP on the ZT NIC. Mapped Drives work as well as Exchange. WTF!

it's the round robin DNS thing.. aka you got lucky!

I assumed form the statement that he changed no DNS settings.

If that is the case, then it is NetBIOS over ZeroTier.
If he changed the DNS , then yeah, a crapshoot.

I have made no DNS changes since I was told to do FQDN names yesterday.

I was referring to the client you just set up. did you change his ZeroTier adapter to have a DNS value? Not to changing server side DNS settings.

Sorry - When I said no Static IP on the ZT NIC I meant didn't set static DNS.

Good, then you are working as it is intended. You are resolving things by NetBIOS.

DNS has nothing to do with it since you did not set an address.

But shouldn't the other machines be working in the same fashion?

I mean without the static DNS settings?

Yes. Your one specific non working example was getting a DNS result from its local connection and was causing your problem. I suspect something was resolving weird from the AT&T IPv6 DNS that was listed.

Dashrender

But relying on NetBIOS - come on, really? I don't want to hang my hat on that nail.

adam.ierymenko

Just wanted to ask how this was going in general.

WLS-ITGuy

@adam.ierymenko

It is quite odd. I have a few machines that are working without static DNS set for the ZeroTier NIC. But most mapped drives do not work unless I have static DNS set but then Exchange doesn't work.

Does the FQDN that you use for Outlook/OWA exist the same on your internal and external networks? But first, is your internal domain name the same as your external one? i.e. Spit horizon?

Yes, unfortunately, the domain was set up before I got here. wls.wels.net - I wanted to change it but knew it would be a huge undertaking and wasn't sure I wanted to do that in my first 4 months. I am thinking of redesigning the domain structure from the ground up this summer.

The FQDN internal is wls-exchange.wls.wels.net and the external is mailhost.wls.wels.net

Jeff

I would assume that DNS only has a small role in the issue. I have both internal DNS servers set in ZT with FQDNs but I have 3 or 4 that cannot see mapped drives. using the FQDN.

Would it make sense to map the drives using the ZT ip?

Jeff

Dashrender

@WLS-ITGuy said in ZeroTier Question:

The FQDN internal is wls-exchange.wls.wels.net and the external is mailhost.wls.wels.net

Are you resolving both of these address internally and externally? If not, that's your problem.

I wouldn't want to if I could help it.

When you ping the server by hostname that holds the shares, what IP do you get back?

@Dashrender

off campus

Mailhost.wls.wels.net - 74.62.99.50
wls-dc01.wls.wels.net - does not resolve

On Campus

mailhost.wls.wels.net - 172.16.0.14
wls-dc01.wls.wels.net - 192.168.191.181 (ZT IP)

WLS-ITGuy

@Dashrender
I was and it was being reported that connections were timing out.

I don't have access to the machines that were having the issues at this time to further troubleshoot.

wls-dc01.wls.wels.net - 192.168.191.181 (ZT IP)

So when you are off campus, what DNS server is your machine using?

Did you change the order of authority for your network adapters? ZT needs to be first. This should make it's DNS servers first also. This way, your computer should always be using the DNS servers of your internal network, not of whatever location you happen to be at that time.

So when you are off campus, what DNS server is your machine using?

This depends on the user. If the ZT NIC doesn't have a static IP they are using their ISP.

Did you change the order of authority for your network adapters? ZT needs to be first. This should make it's DNS servers first also. This way, your computer should always be using the DNS servers of your internal network, not of whatever location you happen to be at that time.

Yes, ZT is always first.

I will have access to two machines in about 30 minutes. One on campus and at least one off campus.

DNS is completely your issue. There is no problem here except DNS.
